G-As'f Bonne-R5 Application-'filed november 30; 1923; serial' No. 677,674, and in Ausnianeeember.15,?192af This invention relates toV gas burners ofj thef'typewherein an automatic cut-off'of'the' gas-'flow 'isaccompllshed whenever the burner goes out; i

One importantobjectiof the invention 1s to provideanovel, economically constructed;

and improved gas burneriof this type.

AT second'important-object of the invention. is to: provide a gas burner wherein ther controllingyalve will be held open so long as;

the burner' isialight.

With 'the above and other objects in view as will be hereinafter apparent,V the inventionfconsists 'in general of certain novel details of' Construction and combinations of parts hereinafter fully described, illustrated in the a'cco'mpanying drawings and specifically 'claimed i V In the accompanying,drawings like characters of reference indicate like parts in'thevided on one end with a valve 16 of the needle valve type and arranged to close the opening in the nipple 12. The shank or stem is gripped by the member 14 and the latter depends from a slide 17 which is actuated by a lever 18 providedr with a thumb-piece 19, the lever normally being retracted by a. spring 20.

At the other end of the apparatus there is provided a burner 21 having gas holes 22 therein. Extending forwardly of the burner 21 is a pair of fixed jaws 23 one of which has a spring'pressed member 211 projecting therethrough. Underneath the burner is provided aV by-pass 25 having an opening 26 which is located just beneath a bridge 27 extending between the grips 28 of a horse shoe shaped member 29. This member 29 receives the upper end of the stem 15 as indicated at 30.

In operation it may be supposed that the valve is closed;l Upon depressing the `thumb= mixture flowsthr-ongh the openings 22 and. maybe lit. Another part fiows through-the openingh26 and-:beats theV bridge 27.V Oonsequently this bridge expands, forces the.

grips28 outwardly so thatithey seizethe members 23 an'd'thereby h'old'the 'valveplfi'' away from itsV opening, even though the SpringsQO-urg-es it back'wardly; In addition,`

in order to prevent too much closing of the jaws or'grips 28 there is provided a prong 311 which extends from one grip toward the other;-

Therev has thus been' provided a' simple and efiicient device'of'thefkind described` a'nd 1 for the purpose specified."

Itiis obvious that minor changes 1may be made-'inl the form and constru'ction of the in-V vention without departing froml the material.

spiritl thereof.r It'is not, therefore, desired toqconfine the inventionv to the exact form.: herein shown and described, but' it is desired to'include all such'as properly come Within the scope claimed.

Having thus described the invention, what is claimed as new is:

1. In combination, a gas burner having a gas inlet, a shutt-ing-oif member to control admission of gas to the burner and a thermostatic looking device located near the burner flame and including a rigid looking member to hold the shutting-ofi member in its open position and a resiliently supported lock pin attached to the said rigid locking member.

2. In combination, a gas burner having a gas inlet, a valve movable toward and from said inlet to control admission of gas to the burners, a stem carrying said valve, a pair of fixed jaws, a U-shaped head member having arms constituting grips and slidable between said jaws, said head member being connected to the valve stem at the end remote from the valve, a bridge piece connecting the arms of the U-shaped member, and a branch leading from said burner and terminating beneath the bridge piece.

3. In combination, a gas burner having a gas inlet, a valve movable toward and from said inlet to control admission of gas to the burners, a stem carrying said valve, a pair of fixed jaws, a U-shaped head member having arms constituting grips and slidable between said jaws, said head member being connected to the stem at the end remote from the valve, a bridge piece connecting the arms of the U-shaped member, a branch leading from said burner and terminating beneath the bridge piece, and yieldable means carried by one of said jaws against which one of the grips engages.

li. In combination, a gas burner having a gas inlet, a valve movable toward and from said inlet to control admission of gas to the burners, a stem carrying said valve, a pair of fixed jaws, a U-shaped head member having arms constituting grips and slidable between said jaws, said head member being connected to the stem at the end remote from the valve, a bridge piece connecting the arms of the U-shaped member, a branch leading from said burner and terminating beneath the bridge piece, yieldable means carried by one of said jaws against which one of the grips engages, and means to limit the inward movement of the grips with respect to each other.

5. In combination, a gas burner having a gas inlet, a valve movable toward and from said inlet to control admission of gas to the burners, a stem carrying said valve, a pair of fixed jaws, a U-shaped head member having arms constituting grips and slidable between said jaws, said head member being connected to the stem at the |end remote from the valve, a bridge piece connecting the arms of the U-shaped member, a branch leading from said burner and terminating beneath the bridge piece, yieldable means carriedby one of said jaws against which one of the grips engages, means to limit the inward movement of the grips with respect to each other, and manual means for operating said valve.

6. In combination, a gas burner having a gas inlet, a valve movable toward and from said inlet to control admission of gas to the burners, a stem carrying said valve, a pair of fiXed jaws, a U-shaped head member having arms constituting grips and slidable between said jaws, said head member being connected to the stem at the end remote from the valve, a bridge piece connecting the arms of the U-shaped member, a branch leading from said burner and terminating beneath the bridge piece., yieldable means carried by one of said jaws against which one of the grips engages, means to limit the inward movement of the grips with respect to each other, and manual means for operating said valve, including a support for said stem adjacent the valve provided end, said burner having a slot through which the said support passes, a slide on said burner carrying said support and having an upward projection, a bell crank lever having one arm engaging said projection and the other arm constituting a finger piece, and a spring engaging said lever to move it in a direction to cause the valve to open.

In testimony whereof we affix our signatures. Y
